BMW's innovative iDrive was introduced in 2001, and a dozen years later, automakers are still learning hard lessons about what consumers want in their infotainment systems. In response to owner feedback - and a few media drubbings - about the delayed and occasionally fickle responses of its CUE (short for Cadillac User Experience) system, Cadillac has told Wired that it's going to issue an update this year.

Coming for the XTS and ATS, the new software will mean quicker haptic feedback to driver inputs on the touchscreen and the buttons, and snappier responses on screen. Down the road, Cadillac's VP of marketing says that a different mix of screen controls and hard buttons is "something you'll be seeing in the future" - the system is presently a mix of touchscreen-based controls and capacitive-touch switchgear - there are no knobs or physical pushbuttons to speak of, and the omission of both has proven to be a divisive issue among consumers and industry pundits.
